14 gfs2_grow expands a GFS2 filesystem after the device upon which the
15 filesystem resides has also been expanded. gfs2_grow expands the GFS2
16 filesystem to utilize any unused space between the current end of the
17 filesystem and the end of the block device. When this operation is
18 complete, the resource group index for the filesystem is updated so
19 that all nodes in the cluster can use the extra storage space that has
20 been added.
21
22 See lvmlockd(8) for the procedure to extend and refresh the logical
23 volume prior to running gfs2_grow.
24
25 The DEVICE or MOUNTPOINT arguments must be paths to mounted filesys‐
26 tems; expansion of unmounted filesystems is not supported. gfs2_grow
27 need only be run on one node in the cluster. The other nodes will see
28 the expansion has occurred and automatically start to use the newly
29 available space.
30
31 gfs2_grow must be run as the superuser. When the filesystem cannot be
32 resized due to detected errors, gfs2_grow will leave the filesystem in
33 a consistent state.
34
36 -D Print out debugging information about the filesystem layout.
37
38 -h Prints out a short usage message and exits.
39
40 -q Be quiet. Don't print anything.
41
42 -T Test. Do all calculations, but do not write any data to the disk
43 and do not expand the filesystem. This is used to discover what
44 the tool would have done were it run without this flag. This op‐
45 tion can be used to display the current state of a mounted GFS2
46 filesystem.
47
48 -V Version. Print out version information, then exit.

52 Shrinking GFS2 filesystems is currently unsupported.
